[Serusers] Xten-RTPProxy choppy audio

[Adrian Georgescu]

The problem is that every few seconds there is a gap of half second in  
the audio stream (quality-wise the conversation is unacceptable) when  
using Xten softphone X-lite or X-PRO on either Win or Mac via RTPProxy.  
I can consistently reproduce this problem 100% on various systems and  
so do all my customers.

For the sceptics, there is a movie with the problem presented  
(Quicktime is required to play the stream):

XtenProblemWithRTPProxy.mov

and an audio extract:

XtenProblemWithRTPProxy.wav

This is the problem solved in our media proxy.

Regards,
Adrian
